    Coefficient Of Rolling Friction By Ron Kurtus Physics

    Nov 20, 2016 Coefficient of Rolling Friction. by Ron Kurtus. The coefficient of rolling friction is the indication of how great the rolling resistance is for a given normal force between the wheel and the surface upon which it is rolling. This ratio is based on the Standard Friction Equation. Because of the various factors, the coefficient of rolling friction is usually determined experimentally.
